In one embodiment, inner roller heads are arranged on the inner drivingroller body and the inner driven roller body.

In one embodiment, the inner roller heads are of tooth-form structures.

In one embodiment, the outer surfaces of the inner roller heads and theouter roller follow the shape of the structure of a wheel rim.

Compared with the prior art, the wheel rim finishing device of thepresent disclosure has the following advantages.

A machined blank rim is finished to improve the roundness of the blankrim and then improve the finished product ratio and the machiningquality of a wheel. The wheel rim finishing device has thecharacteristics of simple structure, easy operation, high universalityand the like, and may adapt to wheel types with different rimstructures.
